The bill also gives an across the board 1 percent pay raise for services members, establishes protections for victims of sexual assault and allows the transfer of Guantánamo Bay detainees to the United States for trial or foreign countries.

Senators have been working to hold amendment votes, but so far haven’t reached agreement.

“If Republicans refuse to bring their number [of amendments] down to 25, then I will go ahead and support cloture of the bill,” Inhofe said before Reid filed the motion. “If the Majority-side says they’re not going to accept the 25 offer, then I will oppose cloture.”

Lawmakers are rushing to complete work on the bill by Thanksgiving so that House and Senate conferees would have time to report back to both chambers before the end of the year. Congress has passed an NDAA bill for 51 straight years.

Democrats would need 60 votes to overcome a Republican filibuster, but they only have 55 in their caucus.

“I can’t tell everybody in this body how disappointing this would be if we do not finish this bill tomorrow night or Friday,” Levin said. “There is only one week left where both the House and Senate are in session.”
